CHARLES FRED JAHNS, OF FOX LAKE, WISCONSIN.

GRAIN-HARVESTER.

To all whom it 'may concern:

Be it known that I, CHARLES F. JAI-ms, a citizen of the United States,and a resident of Fox Lake, in the county of Dodge and State ofVisconsin, have invented a new and Improved GrailnHarvester, of whichthe following is a full, clear, and exact description.

The object of the invention is to provide a new and improved grainharvester, ar ranged to cut the grain and bind it while in an uprightposition. In order to accom plish the desired result, use is made of acutting mechanism for cutting the grain, carrying means for carrying thecut grain rearward and then sidewise and while held in an uprightposition, and an upright binder for finally binding the grain while inan upright position.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indi cate corresponding parts in all theviews.

Figure 1 is a plan view of the grain harvester; Fig. 2 is an enlargedlongitudinal section of the same on the line 2-2 of Fig. 1; Fig. 3 is asimilar view of the same, on the line 3-3 of Fig. 1; Fig. L is anenlarged rear end view of the grain harvester, part being in section onthe line Liff-l1 of Fig. l; Fig. 5 is an enlarged sectional plan view ofa number of the dividing frames and the longitudinal carrier mountedthereon with the platform and cutter bar removed, the section being onthe line 5-5 of Fig. 6; Fig. 6 is an enlarged longitudinal section ofthe grain harvester, on the line 66 of Fig. 1, and Fig. 7 is a detailsection illustrating parts to be hereinafter specifically referred to.

The main frame A of the grain harvester is provided with a tractionwheel B and a rear supporting wheel or trailer B, and from one side ofthe frame A extends sidewise a platform C, provided at its outer endwith a supporting wheel C adapted to travel on the ground the same asthe traction wheel B and the trailer B. The usual draft mechanism A isconnected with the front end of the main frame A for drawing the grainharvester over the field in the direction of the arrow a, for cuttingthe grain and binding the' same into sheaves, as hereinafter more fullyexplained.

struction is arranged on the forward edge of the platform C for cuttingthe grain close to the ground, and transversely across the cuttingmechanism D extend a series of parallel dividing frames E attached tothe platform C and spaced apart, to divide the grain previous toreaching the cutting mechanism D, each dividing frame E having endlesscarriers F for holding the grain in upright position while cutting it bythe cutting mechanism D, and for carrying the grain rearwardly inupright position and with the butts of the grain resting on the platformC. Over the rear portion of the platform C and in the rear of the frameE and the carriers F extends sidewise an endless conveyer Gr, receivingthe grain in sections from the said. carriers F and carrying the grainin upright position over the platform C in the direction of the arrow b,and finally delivering the grain to an upright binder I-I of anyapproved construction, for binding the grain while in upright position,and resting on the right-hand side of the platform C, the bound sheafbeing finally dropped over the right-hand side of the platform C ontothe ground.

The cutting mechanism D consists of the usual sickle bar D and guardsD2, and the sickle bar D is connected by a pitman D3 with a crank disk Ion a shaft I journaled in suitable bearings on the main frame A andextending rearwardly, as plainly indicated in Figs. 1 and 3. On the rearend of the shaft I is secured a sprocket wheel I2, over which passes asprocket chain I3 also passing over a sprocket wheel I4 secured 011 ashaft I5 journaled on the main frame A. On the shaft I is secured abevel gear wheel I6 in mesh with a bevel gear wheel I7 secured on avertically-disposed shaft J carrying at its lower end a sprocket wheel Jconnected by a sprocket chain J2 with a sprocket wheel J3 secured on avertical shaft J* journaled on the main frame A, and carrying a bevelgear wheel J 5 in mesh with a bevel gear wheel .IG secured on a transtversely-extending shaft K journaled on the main frame A. A sprocketwheel K is secured on the shaft K and is connected by a sprocket chainK2 with a sprocket wheel K3 secured on the shaft B2 of the tractiontraction wheel B is transmitted by the gearing described to the shaft Iso that the sickle bar D is reciprocated to cut the grain.

Each of the dividing frames E is approximately trapezoidal in shape, asplainly indicated in Fig. 6, and each frame supports tiers ofhorizontally-disposed carriers F of differentlength according to theshape of the frame E, as will be readily understood by reference toFigs. 5 and 6. Each tier of the carriers in all the frames except theend frames consists essentially of upper and lower sets of arms F F2adapted to project from opposite sides of a frame E and travelingrearwardly so as to hold the grain in vertical position while being cutby the cutting mechanism D, and to carry the cut-off grain in uprightposition onto the platform C. The upper set of arms F is secured to anendless chain F 2 passing around sprocket wheels F4 and F5, of which therear sprocket wheel F4 is secured on a vertically-disposed shaft L,journaled in suitable bearings in the frame E, as plainly indicated inFig. 6. The forward sprocket wheel F5 is journaled in the frame Ej AEachvof the arms F is provided at its pivotal end with a foot F6 adapted totravel on an arm E forming part of the frame E, so as to hold the arm Fin extended position while traveling rearwardly and to allow the arm tofold on the return or forward movement, it being understood that when anarm F during the return movement passes around the sprocket wheel F5then the foot F5 strikes the forward end E2 of the bar E, whereby thearm F is again extended or swung outwardly into active position. Thearms F2 are pivoted on a sprocket chain F7 passing around sprocketwheels F2, F2, of which 'the rear sprocket wheel F8 is secured on ashaft L journaled in the frame E, while the forward sprocket wheel F9 isjournaled in the frame E. The arms F2 are provided with angular arms F10adapted to engage a bar E2, similar to the bar E, but arranged on theopposite side of the frame E, so that the arms F2 are held projectingsidewise while traveling rearwardly and folded during the returnmovement on that side of the frame E on which the arms F are extended atthe time. The arms F2 are projected sidewise again on traveling aroundthe sprocket wheel F9 and engaging with their arms F1o the forward endof the bar E2.

It is understood that the shafts L and L in each of the frames E carrythe several sprocket wheels F4 and F s of the t-iers of carriers in thatparticular frame E, and the lower ends of the shafts L and L extend intoa recess C2 formed'in the platform C, and on the said lower ends aresecured sprocket wheels L2 and L2, over which pass the runs of asprocket chain L4 passing around a sprocket wheel L5 on the shaft J 4previously mentioned, and rotated from the traction wheel B, as beforeexplained.

The outermost frame E is provided in each tier of carriers F with asingle set of arms F2, and the chain L4 passes at this end over sprocketwheel L5 on a short shaft connected by gear wheels VL7 and L8 to theshaft L on which is mounted the sprocket wheel F2 for chain F7 carryingthe arms F2, the same as in the other frames E. In a similar manner theinnermost frame E is provided with arms F but not with arms F2.y

The arms F and F2 travel approximately at the same speed as t-he forwardmovement of the harvester so that the grain is held in an uprightposition while being cut by the cutting mechanism D, and then the cutgrain is carried by the arms F, F2 rearwardly on the platform C tofinally reach the conveyer G. s

The conveyer G is arranged as follows: On the platform C is arranged alongitudinally-extending barrier or guide wall G, spaced a distance fromthe rear ends of the frame E, and the said barrier G limits the rearwardmovement of the cut grain and guides the latter in a transversedirection from the left to the right while being carried in thedirection of the arrow b by arms G2 arranged in t-iers and projectingfrom sprocket chains G2 passing around sprocket wheels G4, G5, of whichthe sprocket wheels G4 are secured onthe upright shaft J driven from thetraction wheel B,l as previously explained. The sprocket wheels G5 aresecured on a vertical shaft G6 j ournaled onthe lefthand end of theplatform C, the-barrier G and at the rear thereof (see Figs. l, 4 and6). The shaft J previously mentioned is journaled near the right-handside of the platform C and the corresponding end of the barrier G (seeFigs. 1, 3 and 4). The barrier G is provided with lengthwise-extendingslots G7 for the passage of the arms G2. When the grain harvester -isdrawn over the field and a rotary motion is given to the shaft J, then atraveling motion is given to the sprocket chains G3 to cause the arms Gto travel longitudinally in the direction of the arrow b in front of thebarrier G and close to the rear ends of the frames E so that the cutvgrain is taken hold of by the front arms G2 to convey the grain .fromthe'left to the right in the direction of the arrow and to finallydeliver the cut grain in upright position to the binder H for the latterto bind the grain while in upright position.

The vertically-arranged binder H is in detail of the same constructionas the one ordinarily used in the McCormick grain harvesters, so thatfurther detailed description of the said binder H is not deemednecessary, it being, however, expressly understood that I do not limitmyself to any particular form of binder as the same may be varied, theonly requirement being that the binder binds the grain while standing ina vertical position.

It is desirable that the binder H be vertically adjustable to permit ofbinding grain of dierent height and to bring the binding twine thedesired distance from the butts of the grain, and for this purpose thesleeves H and H2 of the binder are mounted to slide on vertical guiderods N, N, supported at their lower ends on a support O attached to theplatform C, while the upper ends of the guide rods N and N are held onan auxiliary frame P forming part of the main frame A. The upper ends ofthe sleeves H and H2 are attached to ropes or chains Q, Q, passing overguide pulleys Q2, Q3 to connect with an arm Q* held on a shaft Q5journaled on the main frame A, and provided with a hand lever Q6 underthe control of the operator and adapted to be locked on a segment Q7attached to the main frame A. Thus by the operator manipulating the handlever Q, the sleeves H and H2 can be raised or lowered in unisonaccording to the height of the grain to be bound at the time.

The crank shaft H3 of the binding mechanism is journaled on the sleeve Hand is provided with telescoping sleeves H, H5, of which the sleeve H5has sliding connection with a vertical shaft R journaled on the mainframe A and carrying a bevel gear wheel R in mesh with a bevel gearwheel R2 secured on a shaft R3 journaled on the support O and carrying asprocket wheel R4 engaged by the sprocket chain I3 previously mentionedand driven from the traction wheel B, so that when the harvester ismoved over the field then a rotary motion is given to the shaft R3 whichin turn rotates the shaft R, and the latter' imparts a rotary motion tothe crank shaft H3 of the binder H. By having the sliding connectionbetween the crank shaft H8 Vand the shaft R,

the binder mechanism can be raised or lowered for binding grain ofdifferent length, without disconnecting the shafts R and H. Guiding armsS extend from the delivery end of the conveyer G and the right-hand endof frame E to the binder H so as to hold the grain in vertical positionduring the time it passes from the conveyer G to the binder H (see Fig.l).

The operation is as follows: When the grain harvester is drawn over thefield then a rotary motion is given to the several mechanisms by thetraction wheel B. As the grain harvester is drawn forward in thedirection of the arrow a., Nthe grain passes between adjacent dividingframes E in which travel rearwardly the arms F and F2 so that the grainis held in an upright position and is cut off by the cutting mechanism Dwhile in such position. The arms F and F2 carry the cut off grainrearwardly onto the platform C, the rearward movement of the grain beinglimited by the barrier G. The arms G2 at the front of the barrier nowtake hold of the cut off grain and push the same from the left to theright in the direction of the arrow I) sidewise over the platform C andwhile the grain is in upright position. The grain is finally passed bythe arms G2 to the binder H which binds the grain while in uprightposition, and the bound sheaves are finally dropped off the right-handside of the platform C onto the ground. In order to deliver the grain insections to the arms G2, it is desirable to provide the rear ends of theframes E with springs E4 extending across the gap between adjacentframes so that the grain accumulates between adjacent frames E untilsulficient grain has accumulated to open the springs E4 to allow thebunch of accumulated grain to pass to the arms G2.

Havingv thus described my invention, I claim as new and desire to secureby Letters Patent:
